SCALE-SCRAP-ING lDEVIC;

SPECIFICATION 'forming pere ef Lettere Patent No. 616,010, dated December 13, 1898. Application filed January 14, 1898. Serial No. 666,598. (No model.)

To all whom t may concern:

Be it known that I, WILLIAM M. REED, a citizen of the United States of America, residing at Bellaire, in the county of Belmont and State of Ohio, have invented certain new and useful Improvements in Scale-Scraping Devices, of which the following is a specilication, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in scale-scraping devices and is adapted to be employed in connection with ordinary rolls, by which the scale may be scraped from the slabs or plates durinfr the process of rolling.

lhe principal features of my invention comprise the spring-pressed scraping-bars that are operated so as to open and admit the slab or plate from the rolls and comprise the means by which the scale is removed from the slabs or plates during the rolling. These bars are of a peculiar form of construction, and they are also 'arranged in a manner to remove the scale from both the upper and lower face of the slab or plate,whieh construction, together with the details throughout, will be hereinafter more specifically described, and particularly pointed out in the claims.

In describing the invention in detail 'refer-` ence is had to the accompanying drawings, forming a part of this specification, and wherein like figures of reference indicate similar parts throughout the several views, in which- Figure 1 is a perspective view of the device with one of its sides or housing broken away. Fig. 2 is a rear View of the machine. Fig. 3 is a front view of the same. Fig. 4 is a transverse vertical sectional view. Fig. 5 is a transverse vertical sectional View taken on the line X X of Fig. 3. Fig. 6 is a perspective view of a portion of the cross-head for the upper scraping-bar. Fig. 7 is a perspective view of a portion of the top cross-head. Fig. 8 is a side view of a portion of the housing, showing the adj ust-able support. Fig. 9 is a detail View of one of the double pulleys. Fig. 10 is a detail and sectional view of one of the single pulleys.

This invention should be considered in connection with Letters Patent granted to me August 3l, 1897, No. 589,370, and is an improvement thereon.

Referring now to the drawings by referenceigures, 1 denotes the bed-plate,which has the side frames or housing 2 formed integral therewith or rigidly secured thereto. Secured to the inner face of the housing or side frames lation to the surface of the slab or plate, thereby causingthe scraping-bars'to remove the scales easier and more effectually'.

Resting upon the adjustable brackets or supports 3 are auxiliary side frames or housing 5, to which are attached a frame 6, by means of which the mechanism which operates the two vertically-sliding plates is supported, as will be hereinafter more fully described. This frame 6 has attached to its,

rear face angle-straps 7, which form guides that hold the lower plate 8 in close engagement with the lower portion of they frame 6, the said plate 8 being provided at its upper end with a cross-head 9, having a V-shaped groove extending the length of its upper face, which receives the lower scraping-bar 10.

The frame 6 is inclined inwardly, and is provided at its point of incline with an opening 1l to permit the slab or plate to pass between the scraping-bars.

The upper scraping-bar 12 is secured in a cross-head 13, which is carried on the lower edge of the upper slide-plate 14., which is retained in engagement with the upper portion of the frame 6 by means of the guides 15, 'secured thereto, and which are of similar construction to the guides 7, provided for the lower plate.

The inclining of the plate 6, it will be observed, places the scraping-bars out of alinevment with each other, and in order to keep the said scraping-bars in proper engagement with their work I make the same springpressed and independent of one another, the

IOO

upper plate being adapted to have sufficient lateral movement to allow the same to accommodate an uneven slab or plate.

The cross-head 13 has arranged therein at its rear end a guide-rod 16, which passes upwardly and engages through slots 17, provided therefor in the heavy lugs 1S, that are formed integral with the frame 6 at its upper end, said guide-rods 16 being retained in position in a slot 17 by means of the nut 19, and having arranged on the same between the cross-head 13 and the lug 1S a stiif coilspring 20. The lower slide-plate is similarly spring-pressed by means of springs 2l, that are arranged on the guide-rods 22, secured in the cross-head 9 and engaging in slots provided therefor in lugs 23, carried near the base of the frame 6.

In orderto simultaneously operate the slideplates, the pressure is removed from the sprin gs operating against the upper and lower plates, and through the tension of the springs the bars are forced tightly into engagement with the plate or slab. I provide suitable bearings 24, which are attached to the face of the frame 6 at a point above the scraping-bars and have journaled therein a shaft 25, which has secured on each end a double pulley 26. To each of these pulleys is attached a chain 27, which is given a half-turn around the pulley and passes downward over a single pulley 28, that is supported on a short shaft 29, carried by the lower portion of the frame 6, the said chain being then carried upward and attached to the ends of the cross-head 9. Also connected to the double pulleys 26 and at a point that is opposite to the side of the pulley on which the chain 27 is connected is a similar chain 30, which is given a half-turn around the double pulley in the opposite direction from that in which the chain 27 is passed over the pulley, said chain 30 being then carried upwardly over a pulley 31, carried by similar shafts secured to the upper portion of the frame 6, and again passed downwardly, where it is attached to the ends of the upper cross-head 13. The upper slideplate is also spring-pressed by means of the central coil-spring 32, arranged on the rod 33 between a bracket 34, secured to the said slide-plate, and a lug 35, formed on the upper end of the frame 6.

The cross rod or shaft 25 is operated by `means of a crank 36, centrally attached thereto and having pivotally connected to its outer end a vertical rod 37, which is connected to the cross-rod 3S, bell-crank in shape at each of its ends, and which is journaled in the side frames or housing 2 and has attached to its one end, outside of the housing, an operatinglever 39.

A receiving-table 40 is also provided at the back of the scraping-bars and is supported upon the auxiliary side frames or housing 5, said receiving-table being provided with a large central opening 41, so that the scrapingbars may be seen by the operator and the slab or plate readily passed into connection therewith. This receiving-table may be readily retained in its position by forming cutaway portions 42 in its sides, in which engage blocks 43, secured to the inner face of the housing. Thus when it is not desired to use the table the same may be readily lifted off its securing-blocks.

In operation the lever 39 is moved so as to operate through the rod 37, crank 36, and shaft 25. The pulleys 26, by means of the chains, owing to their peculiar arrangement and connection with pulleys, serve to open the two slide-gates in order to permit the slab or plate to pass readily between the same, but after which when the lever is released the spring heretofore described will tend to force the scraping-bars tightly into engagement with the slab or plate, so that the latter will in this way during the process of rolling be subjected to the scraping action of the bars and the scale thereby removed from the same.

The slab or plate may be fed between the scraping-bars by any suitable mechanism, as by a pair of powerful feed-rollers arranged in the ordinary way, the slab being carried on a set of double rolls, so as to be guided horizontally over said feed-rolls to the scraping-bars.

Although I prefer to use two scraping-bars arranged as herein shown and set forth, yet it will be observed that the device can readily be arranged so as to use the scraping-bar on but one side of the metal when so desired,

a similar spring-pressed arrangement being provided for forcing the scraping-bar into engagement with the metal.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
